Abstract
An image processing device for performing gray-scale conversion includes a plurality of processing elements which include respective registers and perform the gray-scale conversion in parallel with respect to respective pixels based on data stored in the respective registers. The image processing device further includes a control unit which controls the processing elements such that the registers of a given one of the processing elements store data of a line segment which is selected from a series of line segments representing an input-to-output relation of the gray-scale conversion, the line segment being selected to correspond to an input gray-scale level of a corresponding pixel.
